Parallel Constant Wattage Heating Cable

Parallel Constant Wattage Heating Cable

Parallel constant wattage heating cable

 

Parallel constant wattage heating cable can be used for pipe and equipment freeze protection and process temperature maintenance requiring high power output or high temperature exposure.This type provide an economical alternative to self regulating heating cable but requires more skill for installation and more advanced control and monitor system.Constant wattage heating cables can provide process temperature maintenance up to 150℃ and can withstand exposure temperature up to205℃ with power on.

 

Product specification and model

 

Parallel constant wattage heating cable

 

 

Structure

 

HGW single phase constant wattage heating cable used to freeze protection,heat preservation for all kinds of pipelines and instruments.Application such as factory Zone 1,Zone 2 explosive gas atmosphere area.

 

 

 

1.Tinned copper stranded wire    2.FEP insulation layer    3.FEP insulation layer

4.Ni-Cr alloy wire               5.FEP insulation layer    6.Tinned copper metal braid

7.FEP outer sheath

 

Working principle

 

Two paralleled stranded copper wire as the bus wires with insulion layer FEP ,then wrap the nickel-chromium alloy as the heating wire connet with bus wires at regular intervals,from the parallel resistance,finally covered with insulion jacket FEP.When the bus wires power on,each parallel resistance begin to heat,thus form a continuous heating cable.

Working principle

 

Three paralleled stranded copper wire as the bus wires with insulion layer FEP ,then wrap the nickel-chromium alloy as the heating wire connet with bus wires at regular intervals,repeated cycle connection (like:AB-BC-CA-AB) from the parallel resistance between two phase,finally covered with insulion jacket FEP.When the bus wires power on three phase,each parallel resistance begin to heat,thus form a continuous heating cable.
